Now, we will create a SurfboardMetricManager class that we will use to persist the SurfboardMetricModel instances in an in-memory dictionary. Our API methods will call methods for the SurfboardMetricManager class to retrieve, insert, and delete SurfboardMetricModel instances.
Stay in the metrics.py file in the metrics/metrics/models subfolder. Add the following lines to declare the SurfboardMetricManager class. The code file for the sample is included in the restful_python_2_09_01 folder, in the Pyramid01/metrics/metrics/models/metrics.py file:
class SurfboardMetricManager():
last_id = 0
def __init__(self):
self.metrics = {}
def insert_metric(self, metric):
self.__class__.last_id += 1
metric.id = self.__class__.last_id
self.metrics[self.__class__.last_id] = metric
def get_metric(self, id):
return self.metrics[id]
def delete_metric(self, id):
del self.metrics[id] The SurfboardMetricManager...
